[dpdk-users] Unsupported kernel driver

I'm having trouble getting testpmd to work with an Intel X710. I'm seeing
an unsupported kernel driver error. Based on this page I think I'm using
the correct kernel driver:

http://doc.dpdk.org/guides/nics/i40e.html#recommended-matching-list


Does anyone have any idea what I'm doing wrong?



My system info:
CentOS release 6.5 (Final)
Intel X710 with version 5.05 firmware

Kernel Driver: i40e version 1.5.23 (From Intel)

DPDK version: 17.05
